-# Updating Pinecil V2: How to build BLISP Flasher
+# How to flash Pinecil V2

-_Note: This has been tested on x86-64. The build process also works on aarch64 and armv7._
-
-## Linux Steps
-
-⛔ Do not use the Pinecil DC barrel jack while updating firmware or you may destroy your PC. ⛔
-
-1. **Linux set-up**
-```
-git clone --recursive https://github.com/pine64/blisp.git
-cd blisp
-mkdir build && cd build
-cmake -DBLISP_BUILD_CLI=ON ..
-cmake --build .
-mkdir tools/blisp/data
-mkdir -p tools/blisp/data/bl70x
-```
-  Note: the blisp command will now be in build/tools/blisp/ folder and could later be run with flags as ` ./tools/blisp/blisp` unless you cd into that folder.
-
-2. Get and cp or mv eflash_loader_32m.bin  to  bl70x folder
-```
-/build/tools/blisp/data/bl70x/eflash_loader_32m.bin
-``` 
-   a. Download [eflash*32m.bin here](https://github.com/River-b/blisp/tree/master/eflash).
-   b. Move eflash*32m.bin to the build/tools/data/bl70x folder 
-   b. Move eflash*32m.bin to the folder  build/tools/data/bl70x 
-   c. If it is a Zip, then unzip & move it.
-```
-unzip eflash_loader_32m.zip -d tools/blisp/data/bl70x/
-```
-
-3. **Get V2 firmware** from Github Ralim's IronOS
-
-   a. Download the newest stable [firmware release here](https://github.com/Ralim/IronOS).
-
-   b. Or download the Beta firmware [IronOS here](https://github.com/Ralim/IronOS/actions/runs/3545583488)
-      Scroll to the very bottom of the page and download **Pinecilv2**. This link is to [beta that has BLE and also works for EPR chargers](https://github.com/Ralim/IronOS/actions/runs/3545583488)
-   
-   d. Extract **Pinecilv2.zip** and select a single language file (English = ```Pinecilv2_EN.bin```).
-   
-   e. Move the Pinecilv2_EN.bin (or selected language) into the same folder as the blisp command.
-```
-build/tools/blisp/Pinecilv2_EN.bin
-```
-can delete all the rest of the Pinecilv2**.zip as it is not needed.
-
-4. Connect Pinecil to PC/laptop: long hold [`-`]  , then connect cable. Can release the [-] after about 15-20second. V2 screen should be Empty/black,  if not, then repeat connection, or find another cable/port. Pinecil connects as a serial COM port.
-
-5. If this fails, see [troubleshooting below](https://github.com/River-b/blisp/blob/master/README.md#troubleshooting).
-
-6. If you are in  the folder  `blisp/build/tools/blisp/`   then execute 
-```
-sudo ./blisp write -c bl70x --reset Pinecilv2_EN.bin
-```
-Note: if a different language was selected, replace `Pinecilv2_**.bin` above with the chosen file name.
-
-7. Almost done: unplug from the PC and restart V2. Hold down the minus `(-)` button to see the new version number.
-
-8. Before making menu changes, it is recommended to first [Restore Settings to Default](https://github.com/Ralim/IronOS/blob/dev/Documentation/GettingStarted.md#settings-menu).
-   Simply go to Advanced settings > Restore default settings, confirm using the `(+)` button. This sets all menu items to defaults, keeps the same firmware version, and does not affect any Boot-up logo art if applicable. Setting  defaults first avoids unexpected behavior due to some changes in upgrades.
-   
-9. Congradulations, and [Stay Fluxey, my friends!](https://www.reddit.com/r/PINE64official/comments/xk9vxu/most_interesting_man_in_the_world_i_dont_always/?utm_source=share&utm_medium=web2x&context=3)
-
-## Troubleshooting
-1. If the Pinecil V2 fails to connect to the PC, check the `dmesg` command output.
-
-    a. try different cable: usb-C to C is recommended over Usb-A, especially if you are having issues.
-    
-    b. don't use a USB hub, directly connect to the USB port on the PC or laptop.
-    
-    c. try different Usb ports (usb-c recommended). Sometimes the rear ports on a PC are better because they are directly connected to the motherboard.
-    
-    d. try a different PC/laptop
-    
-2. It is important to hold down the `(-)` minus button _before_ plugging in the Usb-c cable, and do not release the button for another 15-20 seconds. Try to hold it a little longer before releasing if your computer is slow and it is not working. In rare circumstances on fussy USB ports, keep holding the `(-)` for the entire update.
-
-3. If all of this fails, then join one of the [Live Community Chat channels linked](https://wiki.pine64.org/wiki/Pinecil#Community_links) in the Pinecil Wiki as volunteers there might be able to help.
-
-4. Open a an new issue ticket in this Github/Blisp flasher at https://github.com/pine64/blisp/issues
-
-5. See [Pinecil Wiki](https://wiki.pine64.org/wiki/Pinecil) for hardware information.
-
-6. See [Github Ralim's IronOS](https://ralim.github.io/IronOS/#getting-started) for firmware/software information. This is only the Flasher that loads the firmware; all Pinecil firmware documents and menu instructions are in IronOS.

Marek Kraus	cbac0733ee	Final support of flashing on macOS For some reason, macOS have issues with USB CDC, surprisingly, CH340G convertor works just fine. But FTDI and Bouffalo's USB CDC didn't worked. Basically, without writing anything, we don't receive response from board. This was fixed by adding drain after writing BOUFALLOLABRESET handshake + adding drains after every commmand write. Also, for some reason, in USB CDC, the size of USB payload is limited, else it will fail.	2023-01-21 14:34:46 +01:00
